Sorry for the newbie questions here.

I'd like to design a system with a partially filled, atmospheric pressure tank, which is on the collector side and acts as the energy store and the drainback tank. I have found a template with a Chinese tank, which is partially filled with programmable controller, so it looks like what I want to do is possible in Polysun.

My questions are:
  • How do I add a vent to a tank to keep it at atmospheric pressure?
  • Am I missing some obvious drainback templates in Polysun?
  • How do I fit a pressure relief valve to a pressurised drainback system?

Many thanks in advance :)
